A kind of water dispenser
Technical field:
The utility model relates to a kind of drinking equipment, and particularly a kind of water dispenser with refrigerating function belongs to the renovation technique of water dispenser.
Background technology:
At present, have refrigerating function, realize by compressor in the water dispenser of refrigeration, its refrigeration system mainly by compressor, condenser, capillary, be wrapped in the outer evaporimeter of cold tank and form, during the refrigeration system operation, the cold-producing medium evaporimeter of flowing through, carry out heat exchange with the drinking water in the cold tank, thereby reach the purpose that reduces water temperature.Its evaporimeter is that circular copper pipe is entwined by shape of cross section generally, because forming the copper pipe of evaporimeter is that line contacts with the contact-making surface of cold tank, contact area is less, efficient when the gas-liquid two-phase cold-producing medium of low-temp low-pressure and the normal-temperature water in the cold tank are carried out exchange heat in the evaporimeter is lower, make the refrigerating capacity of product effectively not bring into play, energy-saving effect is not good enough.
The utility model content:
The purpose of this utility model is to consider the problems referred to above and a kind of water dispenser that can effectively improve the product refrigerating capacity is provided.The utility model is reasonable in design, good energy-conserving effect.
The utility model is realized by following scheme: the utility model includes the refrigeration system that is connected to form successively by compressor, condenser, capillary, evaporimeter, evaporimeter is wrapped on the cold tank, cold tank is provided with water inlet pipe, outlet pipe, and wherein the contact-making surface of evaporimeter and cold tank is the plane.
The shape of cross section of above-mentioned evaporimeter is oblateness or rectangle or D font.
Therefore the utility model, makes the contact area of evaporimeter and cold tank increase because to adopt the evaporimeter and the contact-making surface of cold tank be the structure on plane, makes product under same equal time, condition with constant power, quickening heat exchange, lifting product refrigeration performance.The utility model is a kind of reasonable in design, good energy-conserving effect, convenient and practical water dispenser.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is wrapped in structural representation on the cold tank for the utility model evaporimeter.
The specific embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, include the refrigeration system that connects to form successively by compressor 1, condenser 2, capillary 4, evaporimeter 6, evaporimeter 6 is wrapped on the cold tank 5, cold tank 5 is provided with water inlet pipe, outlet pipe, and wherein evaporimeter 6 is the plane with the contact-making surface of cold tank 5.Also be connected with drier 3 between above-mentioned condenser 2 and the capillary 4.
The shape of cross section of above-mentioned evaporimeter 6 is oblateness or rectangle or D font.In the present embodiment, the shape of cross section of evaporimeter 6 is oblate.
Efficient when further improving exchange heat, the above-mentioned cold tank 5 outer heat-preservation cotton that also are equiped with.
Refrigeration system of the present utility model is when operation, suck gaseous refrigerant in compressor 1 cylinder, reciprocating motion of the pistons compresses gaseous refrigerant, discharge the cold-producing medium of HTHP, the condenser 2 of flowing through, gaseous refrigerant becomes liquid refrigerant, after passing through filter absorbed moisture content and impurity screening then, enter capillary 4 throttlings, refrigerant pressure and temperature descend, the gas-liquid two-phase cold-producing medium that becomes low-temp low-pressure enters evaporimeter 6, carry out exchange heat with the normal-temperature water in the cold tank 5, reach the purpose that reduces water temperature, liquid refrigerant becomes gaseous state again then, the cooled via return air pipe sucks compressor 1, enters the next round circulation.
